FLUSH-TANK vAnvEj Application filed April 29, 1925. Serial No. 26,698.

Y disc having an inclined surface inclined towards a bracket to which is pivotally connected a float controlled bar, which bar ter minates in a hooked cam member, which engages the inclined surface of the dise, and when the float is in raised position within the tank forces said fla-p valve into close binding engagement with the end of the intake pipe, thereby cutting off the flow of water to theltank` and positively holding the valve in closed position. The valve obviates the use of ground valves and seats, therefore leakage is prevented.l Y

With the above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawing, described Vand claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is 3 forming an extension of the intake pipe,

which sleeve has its upper end provided with an annular flange 4, the upper side 'of which is provided with a valve seat 5. Secured to the annular flange 4 adjacent one side thereof at 6 is a flexible flap valve 7,

which flap valve has its upper side 8 provided withV a disc 9. The disc 9 has its upper face 10 inclined downwardly towards the Vupwardly extendlng'bracket 11 carried by the flange 4, and when forced downwardengagement with the valve seat 5 for preventing flow of water into thetank, however when the flap valve is` released it will move upwardly rapidly, thereby allowing a maximum flow of water into the tank and causes thevtank to rapidlyfill. As the level of the water within the tank 1 rises the float 12 is raised and the float arm 13 is rocked on its pivotal `point 14, thereby forcing its hooked cam member 15 downwardly in engagernent with the upper inclined surface 10 of the disci), consequently the flap valve 7 will be closed and the flow of'water to the tank will'be cut off, however when the float lowers a relatively large amount of water will be quickly discharged into thev tank, thereby obviating objectionable noises as is now the difficulty with valves at present constructed. y

It will be noted that the hooked cam member 15 of the'arm 13 will limit the extent of opening of the valve bythe engagement of said arm with a stop 16, therefore it will be seen that the valve 7 will open to an angular position in a plane at an lacute angle to the valve seat 6, consequently the water which flows up through the supply pipe 2 will be deflected laterally into the tank, thereby preventing water from being projected against the top ofthe tank or above the tank.

ly forces the flap valve l7 into close binding f y rFrom the above it will be seen that a flush A tank supply pipe valve Vis provided, which is simple 1n construction, positive in its operation, and one which will give a maxi! mum vamount of flow of water .during the. tank filling operation in the minimum amountrof time, and one wherein objectionable noises are obviated.

The invention having vbeen set forthrwhatf,v

is claimed as new and useful is The combination with the intake pipe of a flush tank, of a horizontally disposed valve opposite side thereof from the upwardly extending bracket, a disc carried by said flap valve having an inclined surface, said flap valve cooperating with said valve seat, a float controlled rocker arm pivoted to the upper end of the upwardly extending bracket, a. Cain carried by the rocker arm and cooperating with said inclined surface of the disc and forming means for forcing the Hap valve into close binding engagement with the Valve seat and for rapidly allowing the opening of the flap valve dur- 10 ing an intake operation.

In testimony whereof I hereunto affix my signature. v
